摘　　要：在对模型试验分析的基础上,指出钢筋混凝土梁协调扭转设计的关键是控制扭转角,讨论了正常使用状态下钢筋混凝土梁扭转角的控制值及抗扭刚度,并基于上述抗扭刚度分析其塑性协调扭矩及抗扭刚度调整系数。还讨论了影响抗扭刚度调整系数主要因素,给出了抗扭刚度调整系数的范围。研究表明,在一定条件下,可获得较大的调整幅度,有利于指导工程设计。Based on the analysis of model test,it is pointed out that the design key of compatibility torsion of reinforced concrete is to control the twist angle.The twist angle controlling value and the torsional stiffness of reinforced concrete beam are discussed under regular service state.Meanwhile,the plastic compatibility moment of torsion and the adjustment coefficient of torsional stiffness are analyzed.The main influence factors about the adjustment coefficient of torsional stiffness are discussed.Finally,a wider adjustment coefficient of torsional stiffness is presented and it will be propitious to design.
